Goggle device and spectacle frame thereof

Abstract

The present disclosure discloses a goggle device and a spectacle frame thereof. The spectacle frame includes a buckling structure arranged on an end portion thereof. The buckling structure has an accommodating space and an entrance in spatial communication with the accommodating space. The buckling structure includes a cantilever arranged in the accommodating space and a retaining wall that is arranged in the accommodating space and is spaced apart from the cantilever. A free end portion of the cantilever is arranged adjacent to the entrance, and the cantilever is rotatable between a lock position and an unlock position. When the cantilever is at the lock position, the free end portion shields the entrance. When the cantilever is rotated to the unlock position by an external force, the free end portion does not shield the entrance, and the cantilever is deformed to store an elastic force.
